1. Field of the Invention
The present invention relates to lug nut removing devices and more particularly pertains to a new lug nut removing device for simultaneously removing a plurality of lug nuts.
2. Description of the Prior Art
The use of lug nut removing devices is known in the prior art. U.S. Pat. No. 6,305,245 describes a gear assembly that may be used for removing multiple lug nuts. Another type of lug nut removing device is U.S. patent app. 2002/0117027 A1 which again described a gear assembly that may be used to remove multiple lug nuts. U.S. Pat. No. 5,074,170 describes an adjustable device for allowing the removal of lug nuts at varying positions with respect to each to each other.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a device which includes couplers and shaft for attaching sockets thereto to facilitate the removal of lug nuts. Additionally, a removable secondary handle would aid a person in removing lug nuts to gain the proper leverage that would be required while removing simultaneously removing a plurality of lug nuts.
To this end, the present invention generally comprises an air gun that includes a cylindrical housing having a front end. A cover is mounted over the front end. A drive axle is mounted within the housing and is rotated when air flows through the air gun. A primary gear is attached to the drive axle and is positioned within the housing adjacent to the cover. A plurality of secondary axles extends through and is rotatably coupled to the cover. Each of the secondary axles has a first end positioned within the housing and a second end extending outwardly away from the cover. Each of a plurality of secondary gears is attached to one of the first ends of the secondary axles. The secondary gears are each in communication with the primary gear so that each of the secondary gears rotates when the primary gear is rotated. Each of a plurality of couplers is attached to one of the secondary axles and is adapted for releasably engaging a socket to an associated one of the secondary axles. Each of a plurality of sockets may be attached to one of the secondary axles so that the sockets are rotated when the primary gear is rotated.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A primary gear 28 is attached to the drive axle 22. The primary gear 28 is positioned within the housing 14 and is positioned adjacent to the cover 20. A plurality of secondary axles 30 extends through and is rotatably coupled to the cover 20. Each of the secondary axles 30 has a first end 32 positioned within the housing 14 and a second end 34 extending outwardly away from the cover 20. The secondary axles 30 are each equidistant from an axis of the primary gear 28. Each of plurality of secondary gears 36 is attached to one of the first ends 30 of the secondary axles 30. Each of the secondary gears 36 is in communication with the primary gear 28 so that each of the secondary gears 36 rotates when the primary gear 28 is rotated. It is preferred that there are five secondary gears 36.
Each of a plurality of couplers 38 is attached to one of the secondary axles 30 and is adapted for releasably engaging a socket 40 to an associated one of the secondary axles 30. The couplers 38 are preferably ball detents positioned on the secondary axles 30 and are positioned adjacent to the second ends 34. Conventional sockets 40 employ a depression for receiving the ball detent. The secondary axles 30 also preferably have a square shaped cross-section taken perpendicular to their longitudinal axis.
A gripping member 42 is removably attachable to the housing 14. The gripping member 42 extends laterally away from the housing 14. The gripping member 42 preferably includes and elongated rod 44 having a bend therein adapted for fitting into a similarly shaped track 46 that is depressed into the housing 14. A handle 48 is attached to one of the ends of the rod 44 and extends outwardly away from the housing 14 when the rod 44 is in the track 46. The rod 44 may be removed from the track 46 when the gripping member 42 is not required and for storage purposes.
In use, each of a plurality of sockets 40 may be attached to one of the secondary axles 30 so that the sockets 40 are simultaneously rotated when the primary gear 28 is rotated. The secondary axles 30 are to be positioned so that each corresponds to one lug nut one a tire and thus different versions of the tool 10 will be adapted for fitting different lug nut locations. When a central area of the cap 20 is aligned with the hub of a tire, each of the sockets 40 is allowed to engage one of the lug nuts of the tire and each may be selectively loosened or tightened accordingly.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
